Answer:
56x
Step-by-step explanation:
Think of it an a triangle and a rectangle. The area of the rectangle is obviously 13 x 4x, which is 52x
for triangle, the hypotenuse is C, Right hand side is B and the side that is in the shape is B.
Area of triangle = (bh) / 2
B = 13 - 9, so B = 4
A = 6x - 4x, so A = 2x
the area is 2x x 4, which is 8x.
8x / 2 = 4x
The area is 4x + 52x, so the final answer is 56x
9,000 * 3% = 270
So it would be $270 in sales tax
I assume the equation is
then let 
.
The right side is real-valued and positive, and only on the left side do we have an imaginary term, which tells us
Then
but again we omit the negative solution, so that
Lets look at the info we have:-
400 personal video players and find that 399 have NO defects.
Solve:-
2000 ÷ 400 = 5
So, about 5 of the video players will be defect.
Hope I helped ya!! xD<span />
